Sediment oxygen demand

The model is sensitive to lower river sediment oxygen demand. If the demand is removed, the predicted DO value at RK 3.1 (RM 5.0) is 8 percent higher than the standard condition. [Pg.267]

The determination of the chemical oxygen demand of sediments has been discussed [22, 54], Markert et al. [174] have described equipment for the collection of sediment and determination of sediment oxygen demand by means of a flow-through diffuser. [Pg.368]

Typical values of sediment oxygen demand (SOD) in lakes vary from 0.5 to 5 g/m -day. Assuming a diffusivity of 10 m /s for oxygen in the lake sediments. [Pg.52]

Sediment oxygen demand acts as a sink for oxygen released by roots. [Pg.239]

Metal removal in SSFCWs has been recently focused on metal elimination from synthetic water and different wastewaters,66-86 on the evaluation of the effects of season, temperature, plant species, and chemical oxygen demand (COD) loading on metals removal,87 and on the accumulation of metals in wetland plant species and sediments.88-89 Recent reviews on heavy metal phytoremediation wetlands are also available.48... [Pg.397]

This treatment process employs the use of physical operations such as screening and sedimentation to partially remove suspended solids and organic matter from the wastewater. This process provides the secondary treatment with wastewater that is partially free of solids, in order to facilitate further treatment. The effluent from the primary treatment contains primarily organic matter and is characterized by a relatively high biochemical oxygen demand (BOD).2... [Pg.914]
